Plant lighting 660nm LED, OSRAM 4.24—is it the best in the world?

The main active ingredients in industrial hemp are THC and CBD, which are mainly concentrated in the flower part of the hemp. So, the key to growing hemp is to make the flowers grow strong and healthy. The light sources plants need most are blue light, red light, and far-red light, with Hyper Red (deep red light) at a wavelength of 660nm being the most helpful for promoting plant growth. As a result, the cannabis growing community has increasingly high demands for deep red light.


As everyone knows, the industry's top standard for red light LEDs is the Osram GH cssrm4.24. Its V8 datasheet claims up to 4.14umol/J@700mA, and most people consider this already the ceiling in the LED red light industry.
